It actually wouldn’t reach the same RPMs.  Started stumbling at 9,000 or so.  I forgot to mention that I also went up to a jet of 140 during the race.  Lower power, lower RPMs.  I am SURE it was really rich.  My buddy has the same setup, and he was running a 125 or so……

Nobody near me has had any issues.  Guys at the track said gearing or jetting.  I keep preaching to them that I don’t think it is carb/gearing related since the carb swap has the same exact symptom.

I will as also told that the vacuum lines layout, and length are critical.  I haven’t had chance to look at that yet.

It am assuming that the crank position sensor is the same one as last year…..
